以热轧带钢为基板的热镀锌产品具有生产成本低廉、可生产厚规格2.0-6.0毫米产品等优势，且这些优势是冷基镀锌板很难具备的。在新能源汽车结构件、高端家电外置件、建筑结构件、高速公路护栏、仓储等领域，热基镀锌占有重要位置，且正在逐渐取代价格较高的冷基镀锌板。据了解，现阶段国内仅有极少数钢厂可批量生产，热基镀锌板具有表面质量高、力学性能和成形性能优良、生产成本低的显著特点，受到市场的广泛关注。

Hot-based galvanized products with hot-rolled strip steel as the substrate have the advantages of low production cost and 2.0-6.0 mm thick specifications, and these advantages are difficult for cold-based galvanized plates to have.In the new energy vehicle structural parts, high-end home appliances external parts, building structural parts, highway guardrail, storage and other fields, hot base galvanized plate occupies an important position, and is gradually replacing the higher price of cold base galvanized plate.It is understood that at the present stage, only a few domestic steel mills can be mass produced, hot-based galvanized plate has high surface quality, excellent mechanical performance and forming performance, low production cost, widely concerned by the market.

目前，鞍钢集团钒钛（钢铁）研究院、西昌钢钒、重庆高强三方共同努力，利用现有的钢种化学成分体系，在不增加炼钢记号的条件下，通过重新设计控轧控冷工艺参数和热镀锌工艺参数，完成系列汽车结构用钢开发，有效丰富了产品结构，将创造良好的经济效益和社会效益。

At present, Ansteel group vanadium titanium (steel) institute, xichang steel vanadium, Chongqing three joint efforts, using the existing steel chemical composition system, under the condition of not increase steel mark, through the redesign control cold process parameters and thermal galvanizing process parameters, complete the series of automobile structure steel development, effectively enrich the product structure, will create good economic and social benefits.
